Explore how sensory tests reveal true limits of perception in feeble-minded and normal children—and what this means for understanding intelligence.
This scholarly work presents a careful series of experiments on how people discriminate lifted weights, aiming to separate sensory capacity from purely intellectual factors. The study compares feeble-minded individuals with normal peers, using a standardized procedure to establish norms and evaluate whether differences in weight discrimination reflect sensory ability or cognitive factors.
- Learn how the experiment is designed, including how weights are chosen and how judgments are recorded.
- See how defectives and normals perform at different ages, and how intelligence and age relate to sensory discrimination.
- Understand the implications for diagnosing and interpreting sensory tests in light of mental development.
- Get a sense of how findings from this early 20th-century research fit into broader debates about mind and perception.
Ideal for readers of historical psychology, educational research, and those curious about the roots of sensory testing and its relation to intelligence.
